My nine-year-old son asked me, "So what if we knew the world was going to end in only three or four days, and we only had that long to pack up all our stuff?"
Not sure what use it would be to pack up, I asked, "Where would we go if the whole world was going to end?"
"Mars!" he said, as if it was obvious.
"And we'd need to bring some fires with us so we could melt the ice, so we'd have something to drink. We'd also bring some seeds so we could grow food."
I guess he has his disaster plan all worked out.
